The Krebs Cycle generates 3 molecules of NADH with 3 H+ ions as well as one seperate molecule of FADH2. Both are shuttled to the electron transport chain in the inter-mitochondrial membrane. The NADH is oxidized as its electrons are moved through the first protein in the chain. Ubiquinone (the coolest name in all of Biology) accepts the electrons from FADH2 also oxidizing it. At the end of the chain, the final protein passes the electrons (H+ ions) onto half of an O2 molecule forming one molecule of water.

The first material to enter the Krebs cycle is?
The Krebs cycle is the sequence of reactions by which most living cells generate energy during aerobic respiration. It takes place in the mitochondria, consuming oxygen, producing carbon dioxide and water as waste products, and converting ADP to energy-rich ATP.
What is the continuous movement of water from earths surface to the air and back to earth surface?
The water cycle
What purpose does pyruvic acid serve?
Pyruvic acid (or pyruvate) is simply one of the compounds in the metabolic pathway from sugars to carbon dioxide and water. From pyruvate (a three cabon unit) either one of two reactions can occur. It can react to form lactose or lose a carbon dioxide molecule to become a two carbon unit and enter the Krebs cycle.
What are the different cycles in nature?
A payroll cycle is the determined period of time of allocated hours worked.
Clouds are formed from the process of?
The process that most directly results in cloud formation is Condensation. When condensation is formed, it evaporates into the atmosphere and forms clouds. Most people don't know this, but clouds are actually formed completely from rain, not water vapor. :} The last statement about clouds being formed from strictly rain is incorrect. Clouds are formed from water vapor.
What byproduct of the Krebs cycle?
Acetly CoA is formed before the process and enters the cycle. It is processed through a series of reactions that extract electrons and hydrogen ions. A small amount of ATP is produced and carbon dioxide is released.
What is removed from the molecules during the kreb cycle?
electrons, protons, CO2 and water. btw it is not "kreb cycle" but Krebs cycle (mr. Hans Krebs discovered it ;)
Energy leaves the molecules in the Krebs cycle in the form of?
water
What is the point in cellular respiration where pyruvic acid breaks down to oxygen and water to produce energy?
This is the Krebs Cycle and the Electron Transport Chain. More specifically the Krebs Cycle.
What is end product of Krebs cycle?
CO2 (Carbon Dioxide) molecules are given off as waste gas in the Krebs cycle.
What type of product is formed from the reaction of an organic acid and an alcohol?
an ester and byproduct is water
Is water an end product of fermentation the Krebs cycle or the electron transport chain?
electron transport chain
Where does nadh and fadh go after it leaves the Krebs cycle?
They enter what is called the respiratory chain or ( electron transport chain) where Hydrogen atoms are used to produce ATP and water .
How many water molecules produce in Krebs cycle?
Two: 1) oxaloacetate => citrate 2) fumarate => malate
Why is the citric acid cycle a cyclic pathway rather than a linear pathway?
The citric acid cycle is a cyclic pathway rather than a linear pathway because it is easier to remove electrons and produce CO2 from compounds with three or more carbon atoms that form a two-carbon compound such as acetyl CoA.
What is a series of chemical reactions that produces sugars from carbon dioxide?
The series is called the Krebs Cycle, which is a biochemical pathway that breaks down acetyl CoA, producing CO2, hygrogen atoms, and ATP The series is called the Krebs Cycle, which is a biochemical pathway that breaks down acetyl CoA, producing CO2, hygrogen atoms, and ATP
What is the waste product of cellular respritiaon?
carbon dioxide and metabolic water are waste products of cellular respiration. carbon dioxide is formed in the citric acid or Krebs cycle. metabolic water is formed when hydrogen ions are attached to the final electron acceptor oxygen. hydrogen ions are attracted to oxygen because it has a very high electronegativity.
